FEED-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 783,439, dated February 28, 1905.

Application filed March 2, 1904. Serial No. 196,238.

To all whom, it may concern:

Be it known that I, J AMES M. KELLER, a citizen of the United States, residing at Los Angeles, county of Los Angeles, State of California, have invented and discovered a new and useful Improvement in a Combined Feed- Water Heater and Condenser; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

-This invention relates to improvements in combined feed-water heaters and condensers; and the objects of my improvement are, first, to provide an apparatus for facilitating and .economizing the condensation of feed-water for boilers; second, to purify feed-water to be supplied to boilers of engines, and, third, to reduce the cost and'expense of operating boilers for engines, reference being made to the accompanying drawings,and to the referencenumerals marked thereon.

-The invention consists, essentially, in the construction, combination, and arrangement of the several parts, as will hereinafter be fully described in the specification, shown upon the drawings appended hereto, and specifically pointed out in the claims made a part hereof.

I attain these objects by the construction and arrangement of the parts of the apparatus illustrated upon the accompanying drawings, in which Figure 1 is a view in perspective of my improved apparatus, portions of the casing and other parts thereof broken away; and Fig. 2 is a perspective view of one of the horizontal partition-plates removed from the apparatus, showing a deflecting-plate and an end flange secured thereto.

Similar reference numerals refer to like parts throughout the several views.

- The reference-numerall denotes the casing inclosing the parts comprising the apparatus.

' 2, 3, 4, and 5 represent the horizontal partition-plates of the apparatus, which extend from the front side portion 1 to the rear side portion 1" thereof, forming compartments 2, 3, 4;, 5, and 6, which are separated from each other, except for the passage-ways 2, 3, 4", and 5, the said passage-ways forming the only means of communication for the steam and vapor to pass downward from one of the said compartments to the other. These partition-plates 2, 8, 4, and 5 are identical in construction, except the deflecting-plate attached to the said horizontal partition-plate 4:, which is perforated to permit the oil-pipes 30 and 31, hereinafter referred to, to pass through the same, and the description of one of the said deflecting-plates will serve for all. The said horizontal partition-plates are secured to the front portion 1 and to the rear portion 1 of the easing 1 by means of bolts or rivets 7 7, which pass through perforations 7 7 in the vertical flanges 7 7 and through the edges of the said deflecting-plates. The flanges 7 7" are preferably made a part of the horizontal partition-plates and of the deflecting-plates. To the end of each of said partition-plates opposite to that which abuts against the inner faces of the ends 6 6 of the casing 1 I secure to the upper face thereof the cross-flange 8 by means of bolts or rivets 8, and to the under face of each of the said horizontal partition-plates I fasten the deflecting-plate 9, (shown in full and dotted lines upon Fig. 2 of the drawings,) provided with perforations 7 7 through which the bolts or rivets 7 7 after being passed through the front side portion 1 and the rear side portion 1" of the casing 1 securely hold the said deflecting-plate 9 in position. These deflecting-plates serve to direct the steam and Vapor passing under the said horizontal partition-plate to which it is attached downward upon the adjacent partition-plate immediately below,and the cross-flanges 8 8 retard the steam passing over the said horizontal partitionplates, causing the steam to be deflected-upward again against the horizontal plate immed iately above that to which the said flanges 8 8 are secured, thereby aiding the condensation of the steam in passing through the a pparatus.

To the lowermost partition-plate 5, on the under side thereof depending vertically downward therefrom, I secure in anysuitable manner the downwardly-projecting trap-plates 12 12, extending from the front portion 1 of the casing 1 to the opposite rear portion 1, which downwardly-projecting cross-plates 12 12 extend near to the bottom of the compartment 6 of the casing 1. Projecting upwardly from the bottom of the compartment 6 of the easing 1 and secured thereto are the upwardlyprojecting trap-plates 13 13, which, like the trap-plates 12, extend from the front portion 1 to the opposite rear portion 1 of the easing 1. The said trap-plates 12 12 and 13 13 in the compartment 6 of the casing 1 form traps by means of which the oil taken up by the steam used for lubricating portions of the piston, piston-head, and other parts of the engine found commingled with the water condensed from the steam in the compartment 6" is drawn off through the overflow-pipe 15 from the surface of the water in the said compartment 6".

All the compartments 2, 3, 4i, 5, and 6 are cleaned out by openingthe valve 17 in the blow-out pipe 16 and permitting the steam admitted through the pipe 18 from the exhaust of the main engine (not necessary to be shown) and the steam through the pipe 19,1eading from the exhaust of the pump 20 into the uppermost compartment 2, to be forced through the casing 1 of the apparatus, thereby removing therefrom all fluid foreign objectionable matter therein. Any solid matter not carried off from the said compartments of the casing 1 by forcing steam thercthrough is readily removed through the hand-holes 21 21, which afford easy access to each of the said compartments of the casing, which hand-holes are provided with means for securely closingthe same after the said solid matter is removed.

By means of the pipe 25 the water condensed from. the steam in the compartment 6 of the casing 1, from which the oil hereinbefore referred to has been drawn off from the surface thereof through the overflow-pipe 15, is d rawn from the traps formed by the said trap-plates 12 12 and 13 13 in the compartment 6. The said Water condensed from the steam is drawn out and forced through the pipe 26, a portion of which is coiled in the uppermost compartment 2' of the casing, around which the steam hereinbefore mentioned admitted into said compartment circulates, and is again carried by the pipe 27 from the casing 1 to the boiler of the engine (not shown) for operating the plant.

Extending from end to end of the casing 1 through the deflecting-plate 9 within the compartment 1 thereof are the inlet and outlet pipes 30 and 31, respectively. By means of the former oil from a suitable receptacle (not necessary to be shown) is conveyed therefrom through the casing 1 and there heated, and from the said casing the oil is carried to the lire-box under the boiler (not shown) of the one and is entitled to great consideration in operating large plants where large quantities of fuel are consumed.

The spray-pipe 35. perforated and within the compartment 3' of the casing, is connected with the water-supply system in the street where the plant of which the said casing is a part is located. The said spray-pipe is designed to convey water to the casing 1 whenever there is a deficiency of the same therein.

The numeral 37 refers to the vent of the apparatus for the escape of steam when the quantity and pressure of the same has become too great.

It is obvious that many variations and changes in the details of construction and ar rangement of my invention would readily suggest themselves to persons skilled in the art to which it appertains and still be within the spirit and scope of my invention.

I do not desire to confine this invention to the specific construction, combination, and a1:- rangement of parts herein shown and described, and the right is reserved to make all changes in and modifications of the same as come within the spirit of this invention; but I do desire to secure as my invention all features of construction and equivalents thereof that come within the scope of my improvement, as herein shown and described, and illustrated upon the drawings appended hereto.
